Cyanine dyes feature a polymethine bridged chain structure, offering stable fluorescence, a high molar absorption coefficient, and a high quantum yield. These properties make cyanine dyes ideal for labeling biomolecules like DNA and proteins, providing bright and reliable signals for imaging and molecular detection in various research applications.

AxisPharm provides our clients with a full range of CY dyes, such as CY3, CY3.5, CY5, CY5.5, CY7 , CY7.5, and their Sulfo- analogues.

Bulk Inquiry


    Cyanine dyes possess several unique features that set them apart from other fluorescent dyes, making them particularly valuable in various scientific applications:
    1. Broad Spectral Range:
      • Unlike many other dyes, cyanine dyes cover a wide spectral range from the visible to the near-infrared (NIR) region. This broad coverage allows for flexible selection of excitation and emission wavelengths, making them ideal for multiplexing and multi-color imaging.
    2. Tunable Fluorescence:
      • Cyanine dyes can be chemically modified to adjust their absorption and emission wavelengths. This tunability is achieved by altering the length and structure of the polymethine chain, providing customizable dye options for specific experimental needs.
    3. High Quantum Yield:
      • Cyanine dyes often exhibit a high quantum yield, leading to bright and intense fluorescence signals. This efficiency in light emission makes them ideal for sensitive detection, even at low concentrations.
    4. Superior Photostability:
      • Compared to many traditional fluorescent dyes, cyanine dyes are more resistant to photobleaching, maintaining their fluorescence intensity during extended exposure. This stability is particularly beneficial for applications involving prolonged imaging or repeated measurements.
    5. Near-Infrared Fluorescence:
      • Cyanine dyes are among the few fluorescent dyes that efficiently emit in the near-infrared region. NIR dyes are especially useful in in vivo imaging due to their deep tissue penetration and low background fluorescence, enhancing signal clarity in biological samples.
    6. Versatile Conjugation:
      • Cyanine dyes can be easily conjugated to a variety of biomolecules, including proteins, nucleic acids, and lipids. This versatility allows them to be used in a broad array of applications, from simple labeling tasks to complex molecular probes.
    7. Low Background Fluorescence:
      • In the NIR range, cyanine dyes exhibit low background fluorescence due to minimal autofluorescence from biological tissues, which improves signal-to-noise ratios and enhances imaging clarity.
    These unique characteristics make cyanine dyes particularly well-suited for advanced applications in fluorescence imaging, molecular biology, diagnostics, and in vivo studies, where other dyes may fall short in performance.
